Abstract: 
Spermidine effect on biochemical properties consisted of activity of peroxidase, ascorbate peroxidase, relative water content, soluble sugar, and electrolyte leakages in cucumber (Cucumis sativus L. ) was investigated. An experiment was conducted based on CRD with three replications in Islamic Azad University, Shiraz Branch. The first factor was included different irrigation courses at three levels; irrigation every other day, irrigation three days in between and irrigation five days in between. Second factor was included foliar application with three different concentration of spermidine (0, 1 and 2 mM). The results of variance analysis for interaction effect of different courses of irrigation and various concentration of spermidine on peroxidase enzyme activity, ascorbate peroxidase activity and relative water content was significant. The results also showed that plants that received irrigation five days in between with 2mM Spermidine had the highest activity of peroxidase and ascorbate peroxidase enzyme. The interaction of different levels of irrigation and Spermidine foliar application on sugar solution and electrolyte leakages was not significant. In conclusion the effect of 2mM Spermine on peroxidase enzyme activity, ascorbate peroxidase activity and relative water content was significant.
